Abstract: A user equipment (UE) is provided to implement a set of transmit power control (TPC) commands during a time domain window (TDW) including multiple physical uplink shared channel (PUSCH) transmissions. The UE can receive a configuration from the base station to configure the UE to support a power control mode and a timeline measurement related to a PUSCH transmission. The UE can receive a set of TPC commands during the TDW, determine whether a TPC command of the set of TPC commands satisfies a time constraint based on the timeline measurement, determine an effective TPC command for the set of TPC commands based on one or more TPC commands satisfying the time constraint, determine an effective delay for the effective TPC command based on the timeline measurement, and further apply the effective TPC command to a PUSCH transmission determined based on the effective delay of the effective TPC command.

Abstract: Apparatuses, systems, and methods for enhancement in NTN mobility. A cellular base station may serve as a source base station of a handover procedure from the source base station to a target non-terrestrial network (NTN) base station. The cellular base station may configure a parameter associated with the target NTN base station in a handover command, the parameter being related to NTN mobility, and send the handover command to a wireless device for use by the wireless device during the handover procedure. The wireless device may receive the handover command from the cellular base station, and perform the handover procedure using the parameter associated with the target NTN base station.

Abstract: Beam determination refers to a set of procedures for an access node (AN) and a user equipment (UE) to select from among downlink communication beams and/or uplink communication beams for downlink and/or uplink communications, respectively. Often times, the downlink communication beams can include one or more downlink control channels, for example, a Physical Downlink Control Channel (PDCCH) and/or a Physical Downlink Shared Channel (PDSCH), to provide downlink reference signals, such as channel-state information reference signals (CSI-RSs), to the UE. The AN can execute various exemplary downlink beam scheduling procedures to control the transmission of the downlink reference signals, such as the CSI-RSs to provide an example, over the downlink communication beams. In some embodiments, the UE can utilize the CSI-RSs to perform beamforming failure detection (BFD) and beamforming failure recovery (BFR) in the wireless networks.

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing designs for configurations of resource elements to carry reference signals for a user equipment (UE). A reference signal can be processed by the UE according to the configuration of resource elements to carry reference signals. The configurations can be determined by the base station, and received from the base station by the UE. The base station determines the configurations based on information or parameters provided by the UE, e.g., a coherence bandwidth of the channel, a coherence time of the channel, a preference associated with channel status information reference signal, or a preference associated with demodulation reference signal for the UE.

Abstract: The exemplary embodiments relate to a computer readable storage medium, a user equipment, a method and an integrated circuit that perform operations. A user equipment (UE) enters into a first state including one of a non-dormant state or a dormant state with a secondary serving cell (SCell) of a network, the SCell being configured to provide either one of a non-dormant bandwidth part (BWP) as a secondary component carrier (SCC) in the non-dormant state or a dormant BWP as an SCC in the dormant state. The UE switches from the first state to a second state including the other one of the non-dormant state or the dormant state, the switch being based on network configuration, a dormancy timer, or a radio condition.
